PLASTERERS GRILLE;

Application filed February 19, 1923. SerialNo. 620,084;

My invention relates to Plasterers grilles in which the fastening brackets are factorybuilt into the grilles.

An object of the invention is the provision of a fastening bracket that is free to swing from a position in the plane of the grille to a position at right angles therewith, and

vice versa, thereby providing a grille that may be readily rolled up in close-fold order for transportation, and readily unrolled for applying it to the face sidefof a wall or the like.

A further object is the disposition of the brackets on the grille in such a manner that they may be made to slide longitudinally as well as oscillate, and thereby permitting them to be readily manipulated by the operator for moving them from the plane of the grille to a position for applying them to the wall or like surface for operatively applying the grille.

A still further objectis the provision of a spacing element forming a portion of the bracket, operatively slidably carried by thedriving element.

A still further object is'the provision of a fastening bracket for attaching a plasterers grille to the'wall boards of structure, comprising a spacing element disposed on the forward end of a driven. element and normally held thereon against movement relative thereto by providing the bracket with a metallic coating extending across from one of said elements to the other element and preferably applied by immersing the bracket in molten zinc, or the like, which coating is intended to rupture when the driven element is operatively forced into the wall boards against which the spacing elements are seated,'.thereby permitting the latter to slide towards the upper end of the driven element for engaging and binding the grille therebetween.

With the foregoing and still further 0b.,

jects and purposes in View which will ap pear as the description proceeds, my invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

twobrackets suspended from portions of the grille before attaching them to the wall.

' Figure 2 is a; vertical sectional view through the wall and side elevations of two of the brackets, of which the upper bracket is shown in its final position. after being driven into the wall as far as it is intended to go, and the lower bracket. in its initial position ready to be operatively projected thereinto. x

Figure 3 is a side elevation of one of the brackets suspended from one of the wires forming a portion of the grille.

Figure 4 is aside elevation of a bracket oscillatorily suspended at its opposite end. I Figure 5 is a side view of a bracket disposed horizontally. s

Figure 6 is a cross section on line 66, Fig. 3.

. Figure 7 is a plan view of one of the spacing elements in a modified form. I Referring to the drawings in detail,

throughout whichlike reference charactersdesignate like parts:.

o The numeralv 1 designatesa plasterers grille, which is similar in construction to what is known as poultry-netting and cone prises a plurality, of wires 2 disposed in a common plane in herring-bone fashion with inter-twisted portions 3, thereby forming meshes 4.

In Figs. 2 to 5 inclusive, and also in Fig. 9, the inter-twisted portions 3 are illustrated by a single wire in cross section. It is to be understood that the single wire shown in said figures shall be taken to mean a pair of 'Wires twisted around each other and be inzoo pair of laterally spaced apart parallel prongs 7, which straddle the portion 3 and are united at one end thereby forming an arched driving head 8 and underneath which an arcuated crotch 9 limiting the longitudinal movement of the prongs in one direction along their supporting wires, and a spacing element 10 comprising a strip of sheet metal having its ends formed into loops 11 to form tion, however, in order to insure the proper locking of the spacing element upon the prongs, the assembled bracket, after it is mounted in its position on the grille, is subjected to galvanization thereby providing a continuous metallic film overlying the contacting points between said elements and galvanically applied to both.

After the assembled bracket has been mounted in its position on one of the portions 3, it may be oscillatorily suspended from either end asshown in Figs. 3 and 4, or it may be moved longitudinally of itself as shown in Fig. 5.

i t will be observed that in Fig. 1 the spacing elements are secured to the prongs 7 with the bridge portions 13 disposed on the right hand side of the brackets, while in Figs. 2, 3, t and 5, they are shown in the fore-ground.

it is obvious, of course, that the spacing -ele ments may be mounted on the prongswith the bridge portions disposed on either side. ln'the modification shown in Fig. 7, the spacing'element is shown with the bridge BX- tending obliquely between the loops 11.

To attach. the grille to the wall boards, designated by the numeral 15, or other supporting surface, the brackets are manipulated one at a time by the operator into the initial position indicated by the bracket adjacentthe lower portion of the drawing representing Fig. 2, namely, with the pointed or forward ends of the prongs engaging the boards on one side of the grille, and the head portions on the opposite side thereof. The head of the bracket is then struck with a hammer or like hand tool, forcing the prongs to move forwardly through the loops 11, against the resistance offered by the contractile tension of the loops upon the periphery of the prongs and against the resistance offered by the galvanic coating in rupturing it, until the prongs are projected a proper distance into the boards with one edge of the spacing element seated against the outer side thereof and the grille wires 3 clamped between the outer edge of said spacing element and crotch .9 (see upper bracket in Fig. 2). r

I claim:

1. A fastening bracket for attaching a plasterers grille to the wall boards of a structure, comprising, a spacing element disposed on the forward end of a driven elementand normally held thereon against movement relative thereto by means of a metal coating extending across from one of said elements to the other element, said coating adapted to rupture when said driven element is .operatively driven into the wall boards against which said spacing element is seated, thereby permitting the latter to move towards the upper end of said driven element for engaging and binding said grille therebetween.

2. A fastening bracket for attaching a plasterers grille to the wall boards of a structure, comprising, a spacing element'disposed on the liorward end of a driven element and norn'ially locked thereon to resist movement relative thereto by means of'a metallic coating disposed on and around the intersect ingportions of said elements, said coating adapted to rupture at said intersecting portions when said driven element is forcibly projected into the wall boards against which said spacing element is seated, thereby permitting the latter to move toward-s the upper end of said driven element for engaging said grille for binding it between said elements.

8. The combination with a grille of the character described, of a fastening bracket permanently carried by the grille and com prising, a two pronged staple straddling a.

portion of said grille, and a spacing element mounted upon the free end of .one of the prongs of said staple. v

4. The combination with a grille of the character described, of a fastening bracket permanently carried-by the grille and comprising, a two p-ronged staple straddling a portion of said grille, and a-spacing element mounted upon the free ends of the prongs of said staple. I

5. The combination with a grille of the character described, of a fastening bracket permanently carried by the grille and comprising, a two pronged staple straddling a portion of said grille, anda spacing element mounted upon. the free ends of the prongs of said staple and connecting said prongs together.

In testimony of the foregoing being my own, I have hereunto affixed my signature this 31st day of January, 1923.
